Exodus 29:5-14, 35-37

“Then take the vestments and dress Aaron in the tunic, the robe of the Ephod, the Ephod, and the Breastpiece, belting the Ephod on him with the embroidered waistband. Set the turban on his head and place the sacred crown on the turban. Then take the anointing oil and pour it on his head, anointing him. Then bring his sons, put tunics on them and gird them with sashes, both Aaron and his sons, and set hats on them. Their priesthood is upheld by law and is permanent.

“Do everything for the ordination of Aaron and his sons exactly as I’ve commanded you throughout the seven days. Offer a bull as an Absolution-Offering for atonement each day. Offer it on the Altar when you make atonement for it: Anoint and hallow it. Make atonement for the Altar and hallow it for seven days; the Altar will become soaked in holiness—anyone who so much as touches the Altar will become holy.
